Specification of Letters Patent.

Patenteareb. 24., i914.

Application filed September 19, 1913. Serial No. 790,595.

To all whom it may concern Be it known that I, CHARLES E.` GODLEY, a citizen of the United States, and a resident of Detroit, in the county of VWayne and f; State of Michigan, have invented a new and Improved Lamp, of which the following 1s a specilication.

This invention relates to a lamp adapted for use on automobiles, launches and wherever else a headlight may be desired, and it consists in a lamp door that is strong and dust-proof, and at the same time inexpensive to manufacture.

It further consists in the novel details of construction shown in the accompanying drawings and particularly pointed out in the appended claims.

In the drawings, Figure 1 is a bottom plan view of an automobile lamp embodying this invention. Fig. 2 is a section on the line 2 2 of Fig. 1.

Similar characters of reference refer to like parts throughout the several views.

It has been customary to make the lamp lens or door frame of a single heavy solid brass member. This construction results in a waste of material. At the same time, the heavy door frame, when once distorted, is not easily bent back into proper shape, nor does it conform readily to inaccuracies in the lamp-frame. As a result such lampdoors are liable not to be dust-proof, and the reflector consequently may soon become coated and dim. These difficulties are severally overcome in this construction wherein 1 indicates the lamp body, which is preferably substantially parabolic in longitudinal section as shown. The lamp body is made of a thin sheet 5 of brass, extended in the form of a cylinder 6 having an inturned annular front or flange 7.

Mounted on the body, preferably by means of a hinge 3, is a door 2, consisting of a ring and a lens supported thereby. The side of the door opposite from hinge 3 may be secured to the body by a hinge 4, similar to hinge 3, the hinge pin thereof serving as a locking pin to hold the door in position.

The main lens ring 8, preferably of sheet brass, and substantially semi-circular or oval in cross-section, terminates at the edge nearest the lamp body in a rentrant cylindrical bead 9 and an inturned annular flange 10. The opposite or front edge of the main lens ring 8 :lits resiliently against the lens 11, as indicated at 12. To the inner surface of the ring is attached, by brazing or otherwise, a circular bar 13, having an edge portion 1f1-curved to fit the inner surface of ring 8 to permit a rigid connection. The inner edge of this bar 13 is beaded at 15 to form a retaining seat for the resilient or wire ring 16. The ring 16, bar 13, and resilient portion 12 of lens ring 8, together form a retaining means for holding the lens in position. J

The reflector, indicated at 17, is attached to the lamp body in any suitable manner. This reflector, which is preferably of sheet metal, is beaded at 18 and extends backward from the bead in the form of a cylinder 19, linally terminating in an annular flange 20; and within the bead 1S is secured a cushion-cord 21 that is adapted to cushion the lens against the reflector.

It will be seen that the lens retaining ring herein shown is simple and strong and that it may be made of very light material; also that the ring may be readily sprung slightly to conform to inaccuracies in the lamp frame, and that the door is thereby rendered dust-proof. The details of the ring may obviously be changed within certain limits without losing any of the advantages of the construction shown. Such details I regard as within the scope of my invention and I intend to cover them by the subjoined claims.

Having thus explained my construction, what I desire to secure by Letters Patent of the United States is 1. A lamp comprising a sheet metal lampbody having a cylindrical extension terminating in an annular in-turned front formed integrally therewith, and a lens-door com prising a main ring of sheet metal curved in cross-section, and having at the edge nearest the lamp-body a rentrant bead adapted to engage resiliently against the outer surface of the cylindrical extension, said rentrant bead terminating in an in-turned annular flange that bears against the annular inturned front of the body portion.

2. In a lamp, a lens door comprising a main ring of sheet metal, curved in crosssection, having at its edge nearest the lamp body a rentrant bead and an annular flange extending inwardly therefrom, and its opposite or front edge engaging with the lens, a sheet metal circular bar secured to the inner surfaceC of the front portion of the; ring and extending baekwardly therefrom, said bar terminating in a bead, and. a Wire ring Within the bead, said curved outer edge of the main ring, together With the backivardly extending bar and Wire ring sup- I ported thereby, I in position.

3. In a lamp, a lens door Comprising a main ring of sheet .metal curved in crossseetion, and having an inturned outer edge that bears against the lens, a backwardly i extending sheet metal circular bar secured l to the inner surface of the main ring and serving rto retain the lens CHARLES E.
